Abstract
Abstract A protein rich product which is particularly useful for human consumption is prepared from a cereal grain by rupturing the cells of the cereal grain germ, abrading the ruptured germ to free adherent protein particles from the remainder of the germ cell fragments, and separating out a protein rich fraction low in fiber content from a protein lean germ residue fraction, relatively high in fibrous type materials.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
108 words
A method of preparing a protein rich produce useful for human consumption from a cereal germ which comprises the steps of dry grinding said germ in order to rupture the cells of the germ, making a slurry of said ruptured germ in hexane solvent and agitating said slurry in order to free the protein particles from the germ cell fragments and produce a total mixture of hexane, germ oil and ruptured germ solids, centrifuging said mixture to produce a lighter faction of hexane, germ oil and protein rich germ solids, stripping off the hexane from said mixture, and filtering out said protein rich solids from said germ oil.
Claim 2
Independent Claim
80 words
A method for preparing a protein rich product useful for human consumption from a cereal germ comprising the steps of 1 rupturing the cells of a cereal germ, 2 forming a liquid slurry of the ruptured cereal germ cells, 3 abrading said ruptured germs in the slurry to free the protein particles from the germ cell fragments, and separating out from the slurry a protein rich germ fraction of reduced fiber content from a protein lean fibrous germ residue fraction.
Claim 3
Dependent Claim
12 words
The method of claim 3 wherein the slurry is an aqueous slurry.
Claim 4
Dependent Claim
16 words
The method of claim 3 wherein the liquid of the liquid slurry is a non-polar solvent.
Claim 5
Dependent Claim
58 words
The method of claim 3 wherein the protein rich germ fraction of reduced fiber content is separated from the protein lean fibrous germ residue fraction by passing the liquid slurry through a screen having openings of a size sufficient to allow the smaller protein rich fraction to pass through and to retain the larger protein lean fibrous fraction.
Claim 6
Dependent Claim
12 words
The method of claim 3 wherein the cereal germ is corn germ.
Claim 7
Dependent Claim
13 words
The method of claim 3 wherein the cereal germ is grain sorghum germ.
Claim 8
Dependent Claim
17 words
The method of claim 3 wherein the ruptured germ is abraded by means of an attrition mill.
